Item # 264815 Style RMS-ARM112-FDE UPC 810048490820 Condition New Manufacturer [Armaspec](https://www.kygunco.com/brand/armaspec) Weight 2 lb Good high quality aftermarket safety selectors are one of the most commonly added parts on modern AR-15 rifles and pistols. The ST45 is an ambidextrous 45 degree safety selector for the AR10/AR15 platform. Instead of having a full 90 degree rotation to disengage the safety, this selector is set to fire at around the 45 degree point. This allows the operator to flick the lever to disengage from safety. This safety selector is incredibly smooth and has a super crisp lockup. It is designed for firearms that have the correct "FIRE" markings on the receiver to match the 45 degree fire position of this safety selector. ** WARNING: This product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
